[Q] "SD Card mounted as read-only"?

Hi,
I'm posting this issue second time. I have a class 2 SD card with almost 1700mb of ext3 partition. the problem is that my SD turns to read only when accessing some files from my sd card. it says in the notification SD card mounted as a read only and then say "tap" to resolve the card responded unexpectedly.
tapping on it sometimes help if i remove the files that I was trying to access that created the problem. otherwise it mounts it as read only.

Hi, you sure your card is a genuine one? The problems you are having are identical to what I had. Turns out my 32gb card was in fact an 8gb card, and the problem was when capacity was reached it would go to read only. The only way to rectify this was to take the card out, place it in my PC card reader right click on properties of the drive and run the error checking tool. Hope this helps. Got my money back anyway thought £36 was a bit cheap lol! Try writing a large file to the card using your Computer, this should give you an indication if the card is genuine or not.

Card is genuine. I have placed my card several times in my brothers htc hd and formatted it through windows. its almost 8 gb i checked it on windows. last time I deleted a folder which has wiered name as if the folder was corrupted. I deleted that folder n it was running fine again. but its back again.
mine came with telus, so it should be genuine. what does class signify? like i have class 2, what does it mean?

CLass is the speed of read and writes.
I recently had a problen like this it turned out to be a corrupt file in the .secure folder used for apps to sd.

then I guess its because of corrupt files but why is it so often specially when I copy something from windows.

I had this problem once after disconnecting from a Windows PC, simply connect the sd car directly to a computer and run the windows verification tool, it finds the corrupt file and your sd card starts working again

hey i recently had the same problem ,, but i figured it out and this method should work fine...!!
>First of all you should know how this problem has occurred..??,
well the reason is, we all connect the phone to system in usb mass storage mode ,,but while removing we'll only give safely remove in the system and forget to do the same in the phone ,,,trust me this the core for this problem....sd-card cannot be fully unmounted by system ,,, so you have to manually do this by your phone
so if you are using the sense rom ,,after ejecting the disk in the system ,,,in your your phone's notification area
in ''connect to pc'' menu select charging only .....this will completely unmount your memory card .
>if you are using non sense rom ,,"turn off the usb" mass storage
do this every time you connect your phone to the system ..!!!
ok now solution for your problem..
>reboot your phone to recovery mode using rom manager...
>select partition menu
>now select mount usb storage ,,,
>now you have tow options
1. either you backup every thing and format your sd-card (recommended)
or
2.mount your sd-card and check for errors in windows,,,
this should fix your problem ..
remember ,,next time when you are connecting your phone don't direly unplug the the cable..!!

The Class number represents a multiple of 1 MB/s
So if 2 is written on ur SD card then it means that its capable of a read speed of 3MB/s

- Not always true, its happened to me on several occassions when not connected to PC etc... Flickie HD caused mine
If you have a mac the fix is - disk utilities - repair card
Full format I found to be better though

SD Card is write Only, how can I Fix?

I can't access the recovery anymore, can't connect it for disk drive. ROM MGR can't open the card either. I have Clockwork Recovery & I don't know what to do to get the card back to normal. Suggestions please? How will I access my Root if it's stored on this card? Don't know what to do......
Thanks in Advance...

Sometimes a file on my sd card will become corrupt, causing it to mount read only. I'm wondering if you meant to say your card was read only? If so, try plugging your card into a computer and copying the contents to the PC. If an error pops up about a file, delete that file from the card and you should be good to go. If no error happens, make a backup of the card, then reformat the card on your PC, pop it into your phone and format it again under settings->sdcard. Then just copy the contents from your PC back onto it.

Since this my first post I can't provide a link. This is a copy and paste from a different forum. Worked for me and I didn't have to reformat:
"I approached it without reformatting. I took the SD card out and loaded it into a card reader and looked at the file system on the card. One of my subdirs in my Music directory was corrupted and I wasn't able to delete the folder.
So I right clicked on the removable drive and went to properties.
From there I clicked on the TOOLS tab and then on the CHECK NOW button for error checking.
I ran this a few times until I was finally able to kill the remaining files in that subdir.
I then reloaded the card and everything seems ok, except I need to reload my music."

Can you help with micro SD card

I was wondering if another Desire user could help me out. I had a bit of a problem with my phone and had to switch it off and remove my micro sd card, but when I plugged it into my computer with an adapter there was no useful information on it for me to get back. This either means that this is standard and the micro sd card can only be read properly when the sd card is in the Desire and then plugged in. Or that my sd card has an error.
Could someone please help with this and let me know what files they can see when they put their micro sd card into their computer directly.
The picture is what I see.

Run Checkdisk (chkdsk) then file restoring software, to recover your files.
Then Re-format the card. Happened to me once, everything got meesed up. Re-format helped.

Checkdisk isnt a recovery software, but I ran it already, and I tried the recovery program but I cant seem to be recovering anything but more useless information, I dont know if the data is lost or if its still on the card but only readable through the desire itself.
Can someone please do what I said in my original post and let me know what they can see with just the micro sd card in the computer
Thanks

CHKDSK is scans for harddrive damage and it DOES recover the files, but with the .chk extension.
These are the files on my SD:
Uploaded with ImageShack.us

If thats the case then thanks for letting me know.
I ran chkdsk like this.
Plugged in the micro sd card in the computer, went to my computer and right clicked the SD card, clicked properties, went to tools and then error checking.
Selected both the check for system errors and scan for bad sectors. Started it and 2 seconds later it closes and doesnt actually do anything taht I can see. I go back to the sd card and still nothing has changed.
Where should it be putting the recovered .chk files?

Cant wond scan via windows, so i did it by cmd. Said it couldnt convert threads as there is no room. So I'm guessing I have to format it first. I hope this doesnt get rid of my files permanently, I didnt have any other copies of my contacts or anything, and phone is completely broken.

[Q] ES screwed up a simple file operation, now my Note says my SD's blank (it isn't).

*deep breath*
I noticed that my Note II had bounced a rather small app update for lack of space on the phone. Okay, fine. I have a bunch of games on there (GTA is huge) and I guess I have to move/delete some stuff. Then I realize that my camera app has been storing stuff on the phone instead of the 64gb Class 10 Kingston SD card (in b4 "Kingston is crap!"). So I make that change and tell the phone to start saving photos to the SD card. Fine. There are already some photo files on the SD card, so I decide to use ES File Explorer to move the existing photos from my DCIM folder to the one on the SD card. ES tells me everything went fine, and a subsequent check confirmed this. All good so far.
Then I went for a drive and decided to play tracks off my phone. What? Nobody home. No music for some reason. Everything's gone. Fine, I'll look into it when I get home.
This morning: "Oh, I have a photo of that! Let me just get it..."
Nobody home.
Go to ES File Explorer, and all the files and folders on the stupid SD card are 404.
Go to my computer. Connect my Note II and look at the drives on the phone. Windows shows the phone's storage, and shows the card storage, which says there's stuff on there (as in, space is taken up). Click into the drive and... Nothing's there.
Unmount the SD in Settings and put it into a card reader. Maybe the phone's goofing up, right? Windows says that the card needs to be formatted (because it's using an unfamiliar filesystem).
Nuts.
Put the card back into the phone. The phone will recognize the filesystem, so it should be-- What?
Phone says the card is now blank or using an unsupported filesystem.
So there's my problem. How do I proceed? I know that stuff's on there. I just know there's something stupid going on that's preventing me from getting at it.
As long as I can yank my latest photos off there, I don't mind wiping the card and starting over, since it's just media stuff I was keeping on there anyway. What do I use to crack into it?
Thanks in advance for any help you can offer.
UPDATE: Various file recovery apps (in both Windows and the phone) are telling me that the card now has truly nothing on it. There are many, many really great swear words I want to share with you right now, but am prohibited from using on this forum. It actually HURTS not to use them right now.
Why do people seem to have so many problems with 64gb Class 10 cards on the Note II?

I had similar problem, I was trying to use software for SGSII to map SD card as usb flash disk to a PC and it didn't work and when I disconnected I had same symptoms as you. I put the card in reader and connected to PC and repaired with Minitool (just search for "MiniTool Partition Wizard Home Edition"). I lost couple of folders but most of it was ok.
Good luck!

Sounds like You have a Corrupted Boot sector.
Put the SD card in a Card Reader on Your Windows PC.
Open a Command Prompt and Type This - chkdsk /X /F <SD card drive letter>:
If Your SD card is Drive G, It would Look Like This - chkdsk /X /F G:
This will repair the Boot Sector if that is the Problem.
Put the SD card back in Your Phone and You should be Good To Go.

All files on external SD card corrupt after unexpected shutdown

Hey guys and girls!
This morning my phone turned off by itself (13% battery left) and needed somewhat longer than usual to reboot (in the meantime I plugged it back in to the charger). First thing I noticed was that my whole theme got reset as well as it started showing me introductional tips ("long press here to move your apps to the homescreen, ecc.). It also started to update apps in the Play Store even though I set it to manual ... so basically a LOT of things were reset.
The biggest problem I'm having now is though that all my files (pictures, videos, music) that are stored on an external micro SD card are corrupt. It's not possible anymore to open anything. I already removed the micro SD card and put it into an adapter to have a look at the files via the laptop. But nothing, even though the sizes of the files seem OK, I can't open them.
Does anyone have a clue as to what exactly happened here? Are those files lost (at least of some I have a backup) or is there anything I can do to "repair" them? Help is really appreciated, thanks!
PS: Things like the card unmounting and re-mounting never occurred. So I can't tell if the card was dying or if actually the phone ruined my files.

Did you happen to be using a SanDisk SD Card? I've had my 10 brick 2 of those until I switched to Samsung SD Cards about a year ago and haven't had issues since.
I never could manage to recover files from the damaged SD cards.

I have a Samsung SD card and had something similar.
I guess I was on Viper Rom and basically my phone restarted around 15-20% of battery. After a long wait for booting back again, all my settings were gone.
Files and others in the SD card was okay but basically until I formatted the card, I wasn't able to boot into the Download Mode to install a new rom...
I fixed the restart issue by installing the official HTC Rom.

Thanks for your replies.
It is indeed a SanDisk 16GB card. It seems though that the card is still working (no problems accessing it via phone or laptop), just the files appear to be broken. In the meantime I also tried apps like PC Inspector File Recovery, but to no success
I'm still on stock HTC Sense by the way, no root, nothing.
Anyone know though why that happened (resetting everything, etc.)?

Hit me with a PM I'll give you a SanDisk restore tool which works quite ok. there is a huge chance some files can be recovered, some will be damaged though. Don't push any new files on the card after you tried to restore the files

HTC 10-Corrupted microSD card
I know this is an older thread, but I was wondering if there is a solution. I have an HTC 10 which has an micro SD card in it, that is "married" to the phone. When connected to a computer, the computer recognizes the phone, and the microSD card, and begins to load the folders/files. Eventually this process stalls, and the phone/drive is no longer readable by the computer. To get the computer to recognize the phone/card again, I need to restart the phone, but the same thing happens again.
I have like 20gigs of data on the card, and cannot just put the card in a reader, because it's encrypted to the phone. Any possible solutions? It's frustrating to see the files/pictures for a minute or two, and then have them disappear. I have tried copying/pasting the files while they're visible, but this often triggers the computer to no longer recognize the phone/memory card. I've tried to un-encrypt the microSD card, but the phone can't recognize/access the microSD card long enough to complete that process.
Please help if you can.
